If this is students asking other students, I don't know why the parents need to know. If a kid tells some student journalist about his sexual habits or that he drinks and does drugs, that's his business and he will have to live with any publicity that comes with it.
Because these are minors.
When the kids are adults out on their own then (and only then) the parents will have no say.
Up until the sixties most people were bright enough to understand this simple principal without needing someone to explain it to them.
